NAME

PAPI_event_code_to_name - Convert a numeric hardware event code to a name.

SYNOPSIS

Detailed Description

C Interface:

#include <papi.h>
int PAPI_event_code_to_name( int EventCode, char * EventName );

PAPI_event_code_to_name is used to translate a 32-bit integer PAPI event code into an ASCII PAPI event name. Either Preset event codes or Native event codes can be passed to this routine. Native event codes and names differ from platform to platform.

Parameters

EventCode The numeric code for the event.
*EventName A string containing the event name as listed in PAPI_presets or discussed in PAPI_native.

Return values

PAPI_EINVAL One or more of the arguments is invalid.
PAPI_ENOTPRESET The hardware event specified is not a valid PAPI preset.
PAPI_ENOEVNT The hardware event is not available on the underlying hardware.

Examples:

int EventCode, EventSet = PAPI_NULL;
int Event, number;
char EventCodeStr[PAPI_MAX_STR_LEN];
// Create the EventSet
if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
handle_error( 1 );
// Add Total Instructions Executed to our EventSet
if ( PAPI_add_event( EventSet, PAPI_TOT_INS ) != PAPI_OK )
handle_error( 1 );
number = 1;
if ( PAPI_list_events( EventSet, &Event, &number ) != PAPI_OK )
handle_error(1);
// Convert integer code to name string
if ( PAPI_event_code_to_name( Event, EventCodeStr ) != PAPI_OK )
handle_error( 1 );
printf( "Event Name: %s\n", EventCodeStr );
